circuit or reverse polarity conditions and provides a backup safety timer. Reverse Input Polarity: If input power to the charger is connected in reverse polarity, the charger will be protected from damage but will not function. Re-check all input connections and the power source to ensure the proper power and polarities are observed. Battery Condition Pre-Check: Any time a command is given to begin charging a battery, the charger will check the condition of the battery and determine if it is suitable for charging. If an error exists on either output, the respective LED will flash red and green alternately, accompanied by audible tones to note the error. This can occur when a battery is connected to the output in reverse polarity, or if the charger does not recognize a solid electrical connection to the battery on the output. The charger will be protected from damage in either case. Make sure the battery is solidly connected to the output in proper polarity. Current Overload: If for some reason a short circuit condition exists on the input or output, the 7.5A spade (auto) fuse located on the left side of the charger might blow. In this case, make sure the charger’s power switch is in the “off” position. Remove and inspect the fuse. If the fuse is blown, replace with another fuse of the exact same rating. 2-YEAR LIMITED WARRANTY Backup Safety Timer: If for some reason the charger does not (U.S.A. & CANADA ONLY*)
